In the previous study of MongoDB (iii), how to import and export data on the server side and restore the backup, this article describes how to use the Client tool for remote server data backup to local.Take the client tool Mongovue as an example to explain:1. Connect the local server and the remote server database first2. In the local server (127.0.0.1), right-cl

restore the database. This method is simple and clear. Follow these steps: 1. Lock the database or shut down the database. 2. copy the data file to the corresponding directory. 3. Unlock the database or restart the database. Note: If you only need to copy the database named test, you can copy all test. 4.1: how to lock the databaseTo prevent problems caused by changes in data files during backup, use the following command to lock the database: Db

1. Back up database Concept: it refers to backing up all data files and control files of the database, and also backing up parameter files and password files. Note: When backing up a database, do not back up redo logs. 1.1 Consistent backup Concept: Database Consistency backup refers to the method for backing up all data files and control files after the database is disabled. When the SHUTDOWN command is u

insufficient, the index hit rate is low, and the query efficiency is reduced.Currently, the version we use is not very effective.You can use dB. repairedatabase () to sort databases. This process is very slow.In master-slave mode, the master-slave switchover is performed, and the slave database is created again.In a replset architecture, you can stop the database, delete the data directory, and synchronize all data from the replication group,In this case, the oplog size should be considered.A g

authentication is performed, so nothing can be done. After using the test database and performing user authentication, you can view the set in the test database, because test1 can only read and write, therefore, "find" can be successful but "insert" fails. test2 can both read and write data. After using the admin database for user authentication, you can view the list of all databases. In fact, this authentication is not very useful. It is only a method. The safest way is to restrict access. 3)

1. System Backup Based on the degree of preparation of the backup system, it can be divided into three categories: Cold backup, warm backup and hot backup. 1.1 The cold backup system is not installed or configured to the same or s

the collection in the test library because Test1 can only read and not write, so find succeeds and insert fails. Test2 can read and write, and use the Admin database for user authentication to view all database lists. In fact, the use of such certification is not very large, but only a way, the safest way is to restrict access. 3). Data Backup①. Data file backupThe simplest backup is the data file
